Preclinical studies indicate a synergistic effect of radiotherapy treatment (RT) and Immune checkpoint inhibitors (ICI) on tumor growth and metastasis. However, little is known about the immunomodulatory performance of different radioisotopes on the tumor microenvironment. Here, the authors employ alpha- versus beta-particle emitting radiopharmaceuticals in combination with dual ICI therapy and dissect mechanisms of in vivo immunomodulation and timing of ICI administration relative to RT, by comparing responses in immunogenic and non-immunogenic preclinical mouse models.

Multi-omics profiling of 45 human lung samples highlights 80 different cell types along the proximal to distal axis of the lung with certain cell types showing enrichment for disease-associated genes. An immune niche for IgA-expressing plasma cells within airway submucosal glands (SMG) is also identified.

Vaccination is effective in protecting from COVID-19. Here the authors report immune responses and breakthrough infections in twice-vaccinated patients receiving anti-TNF treatments for inflammatory bowel disease, and find dampened vaccine responses that implicate the need of adapted vaccination schedules for these patients.

Petrels are wide-ranging, highly threatened seabirds that often ingest plastic. This study used tracking data for 7,137 petrels of 77 species to map global exposure risk and compare regions, species, and populations. The results show higher exposure risk for threatened species and stress the need for international cooperation to tackle marine litter.

The study provides a comprehensive transcriptomic atlas of the human gastrointestinal tract across the lifespan, highlighting inflammation-induced changes in epithelial stem cells that alter mucosal architecture and promote further inflammation.

Stem-like CD8⁺ T cells specific for lymphocytic choriomeningitis virus are generated early during chronic infection, suggesting that this crucial fate commitment occurs irrespective of the infection outcome.

A comprehensive single-cell RNA sequencing study delineates cell-type-specific transcriptomic changes in the brain associated with normal ageing that will inform the investigation into functional changes and the interaction of ageing and disease.

Dietary protein influences metabolic health and ageing. Here Solon-Biet et al. show that, rather than having a direct toxic effect, dietary branched-chain amino acids (BCAAs) appear to induce hyperphagia, owing to an imbalance between BCAAs and other amino acids, which reduces lifespan as a consequence of obesity.
